The answer, it seems, is that the main site feed is a catch-all that throws everything up in there, regardless of the category.

This is a wordpress.com site, not .org, and my level of customization is limited. There’s a lot I ~can’t~ do on here.

My quickest solution, if cross posting becomes a problem for too many folks, is provide another feed through feedburner or something, with a specific category like say “Gaming” which would exclude everything but the podcast, for example.

If the podcast stuff bothers you a lot, I ask that you have a little bit of patience, I’m trying to upload the 14 older episodes, which is why you are getting a barrage of articles your way. Once I do that and start the 5e podcast, it’ll slow down considerably, and by then I may have the new feed set up in case you’d want to switch to that, which wouldn’t include the podcast.
